Three people were killed, one was hospitalized and one was taken into custody after three unrelated traffic incidents that all took place during a snow-filled Monday in Fairfax County.

The first incident took place shortly before 2 a.m.

Fairfax County police said a patrol officer tried to pull over the driver of a 1999 Dodge Neon on Hilltop Road in Merrifield around 1:50 a.m., when police say the driver sped off.

“As soon as the officer activated his emergency equipment, the vehicle attempted to flee,” said spokesman Bud Walker.

Police said that after a chase, the Neon eventually ran off the road and hit a tree. Police said speed and alcohol were both factors in the crash.

The driver and one passenger were pronounced dead at the scene.

The second passenger was taken to a local hospital with potentially life-threatening injuries. As of Tuesday afternoon, police still had not identified the men, saying that their identification documents were problematic.

“The victims had documents that were not accurate,” said Walker.

The second incident took place on Rugby Road in Fairfax at 2:40 p.m.

There, Fairfax County police said a patrol officer stopped Marc Anthony Dixon, 26, of Reston, as he was driving backwards down the road. Police said Dixon was pulled over, and as he was in a police car after subsequently being arrested for DWI, he began violently kicking the doors and windows.

In addition to being charged with DWI, police said Dixon was also charged with refusing a breath test, providing fraudulent information to police, destruction of county property, driving on a suspended license, and improper backing on the highway. He was taken into custody.

The third incident occurred at approximately 7:30 p.m.

Fairfax County Firefighters said they responded to a vehicle fire in the Crosspointe area of Fairfax County. The vehicle was located on the southbound side of Ox Road, just beyond the intersection of Furnace Road.

Firefighters said they encountered a 1998 Chevrolet Camaro fully involved with fire upon their arrival. They extinguished the fire and said they discovered the body of Fidel Salmeron Jr., 20, of Springfield in the driver’s seat.

According to fire investigators, the car appeared to have slid off the road and the fire appeared to have started in the car’s engine. Fire investigators and Fairfax County Police are jointly investigating the incident. Firefighters said a medical examiner will determine the official cause the death.
